Vanilla Planifolia - Plant Anatomy and Morphology


Plant Anatomy and Morphology

Monocotyledonous plants vs Dicotyledonous plants
All flowering plants can be divided into one of the two categories; either a monocot or dicot plant.
Vanilla Planifolia is a monocot.
Vanilla has a root system that is both epiphytic (that grows on other living trees) and terrestrial (grows on or in or from land). So the term bemiepiphytes is applied to them.
So, the seeds germinate in the soil, and the fine root hairs penetrate in the rich soil while obtaining essential nutrients. These roots are the feeding roots of the Vanilla plant. After germination, the young vines start climbing. New roots are produced with different forms and functions. They vary in length per species. The Aerial roots length of V.planifolia can grow up to 50 cm long. After many years of climbing upwards, you can call the vines
epiphytes. Vanilla Planifolia is a monocot so, that means a Fibrous root system.
Each vanilla flower stays open for 24 hours. In these 24 hours, it needs to be pollinated. You can use natural pollination or hand pollination. Natural pollination can only be done by the Melipona bee. If the bee is not found in the area where you grow the crop, you need to do it by hand.

In Figure 2 you can see the anatomy on a green, ripening, and senescent vanilla pod.It shows the Transverse slices from the stem to the blossom end of a ripening-senescent vanilla pod showing development and progression of oxidation (Conéjéro, 2010).

Vanilla Planifolia - Plant Disease and Insects

Vanilla Planifolia - Plant Disease and Insects  The main factor of damage and a lower vanilla production are diseases. Vanilla grows under a temperature and humidity that is in favour of developing pathogens, which are mainly fungi. So, I will write something about the general production of Vanilla and its diseases (not focused on Madagascar). It is always better to prevent diseases instead of controlling the damage it already did to the crop. Of course, when necessary, you can use a chemical control to avoid environmental contamination.   The main vanilla insect pest is the ‘ Chinche Roja ’ ((Tenthecoris confusus Hsiao & Sailer). It is a small insect that has multiple life stages, including 4 instars. At the nymphal stage, it causes the most damage to the vanilla plant. It is the single most damaging vanilla pest, causing tissue damage in the leaves, stems, and the fruits. The wound of the chinche help to the colonization of fungus and bacteria that cause rot, wilting and

Vanilla Planifolia - Plan Physiology and Growth

Vanilla Planifolia - Plan Physiology and Growth There are different types of photosynthesis; C3, C4 and CAM photosynthesis. Photosynthesis is all about the sun, and capturing that light energy from the sun. And when this happens we have a problem, because CO2 is noticed for photosynthesis and that gets in the stomata through the leaves. And when the stomata go open for the CO2 to go in, we often have a loss of water through transpiration. So, there are adaptations in the chemical reactions that occur. So, first the C3 photosynthesis. It is called this way because; the first compound they form is a 3-carbon molecule. The problem with C3 photosynthesis is that the plant takes up CO2 but is losing quite a lot of it. This all is because of this enzyme that also reacts with O2. This problem does not matter in mild conditions, where the stomata can stay open day in and out because water loss is then probably not a big issue. C4 plants on the other side are trapping CO2 a lot e
